ALWAYS read this skill before touching any Sri Lanka corporate income tax work. Use whenever asked about Sri Lanka company tax for a resident company. Trigger on phrases like "Sri Lanka corporate tax", "Sri Lanka CIT", "company tax Sri Lanka", "30% corporate rate Sri Lanka", "betting and gaming tax Sri Lanka", "liquor tobacco tax Sri Lanka", "Inland Revenue Act 24 of 2017 company", or "year of assessment 2025/26 company". Covers the Inland Revenue Act No. 24 of 2017 as amended by the Inland Revenue (Amendment) Act No. 02 of 2025 (effective 1 April 2025): the 30% standard rate, the 15% concessionary rate on remitted foreign-currency income/services, and the 45% rate on betting/gaming and liquor/tobacco. Out of scope — personal income tax (separate skill), withholding/AIT (separate skill), SSCL, VAT, banking/insurance/sector special regimes, and group/transfer-pricing matters.
